The application of controlled mechanical stress on a wound site can accelerate the wound healing by improving the cellular proliferation during tissue regeneration. To facilitate this there is need to monitor the applied stress around the wound site and hence there is need to develop a biocompatible stress sensor. Here we present the glycine-based biocompatible and flexible piezoelectric stress sensor. The sensor is based on novel piezoelectric composite comprising of piezoelectric y-glycine micro-crystals embedded in PDMS. On application of external force the sensor generates an average output voltage of 250 mV, with current density of 0.010 μA/cm 2 and a power density of 2.5 nW/cm 2 . While the produced piezoelectric voltage helps accelerate the wound healing, the energy generation by the sensor could also find potential applications in self-powered touch sensors. The successful demonstration of presented stress sensor, we will pave the way for their integration on compression bandages and dressings used for chronic wound management.
